Old threads are cool! feel free to re-open them whenever you find a good one . I'm doing a major project on my 2wd cargo van right now and I'm working on some sheet metal parts to catch the air and direct it up into the engine compartment. I am also rigging up a "hot alarm". I found a fan switch that kicks on at 221 deg F and it's going to trigger a piezo alarm & an LED on my dash. I've got too much time and money wrapped up in this new engine to risk overheating it due to a distraction or lapse of attention.

I like my air conditioning and not planning on giving that up any time soon . Tim
